Automated Systems for Manufacturing Patient-Specific Orthopedic Implants and Instrumentation

Abstract

Disclosed herein are devices, systems and methods for the automated design and manufacture of patient-specific / patient-matched orthopedic implants. While the embodiments described herein specifically pertain to unicompartmental resurfacing implants for the knee, the principles described are applicable to other types of knee implants (including, without limitation, other resurfacing implants and joint replacement implants) as well as implants for other joints and other patient-specific orthopedic applications.

AI Technical Summary

Benefits of technology

[0021]In another embodiment, the system automatically finds the best viewpoint to allow the user to perform a design step. This can be facilitated by using the landmark information derived from the patient's anatomical information. For example, the system can find the best view to allow the operator to define the implant's outer profile or contour.

[0023]Alternatively, the virtual template can be user-adjustable. The system can provide an initial default fit of the template and then allow the user to make adjustments or fine-tune the shape or position. The system can update the implant as the operator makes adjustments to the template, thus providing real-time feedback about the status of the implant design. The adjustments can be made, for example, for irregularities of the articular surface including osteophytes or subchondral cysts, or flattening of an articular surface.

[0028]Optionally, the system can allow the user to fine-tune the peg placement, with or without enforcing the constraints.

Problems solved by technology

However, these are not truly personalized, patient-specific or patient-matched approaches.
